This invention relatesto a bobbin clutch attachment for the whirls ofspinning Viframes,-

wherein the whirl is of that type which is pro# vided with atubefspindle rigid with or per-k 5 manently attached to the whirlbasepas distinguished from that type whereinthere is a separate tube ormandrelas shown vinV the U. Sz,

Patent to Ashworth, No. 782,535, dated Febi 14,1905. e l

j i0 There'are certain inherent diiiiclll/'es or disafdvan'tagesVconnected with the use of a split tube or mandrel as disclosed in theabove-4 `mentioned Ashworth patent. In the vcourse:l

of operation, yarn from the bobbin works in-kl Vy side the bobbin andintothe spaces or slots bey, f tween the legs ofthe tube, therebyultimately bindingthe tube veryflrmly and preventing it 'fromVnfunctioning properly, or even rotating. In addition to this, oil worksupinto the split tube and escapes between the legs of the latter"` jonto the yarn and into the yarn box, :causing f n laddedtrouble.

. f The primary objectjof the present inveny o tion, therefore, is .toprovide an Aautomatick g centrifugal bobbin clutch attachment, for

whirls having La rigid or fpermanent,'z--tubeo spindle, .whereby theabove difficulties or disadvantages Vare overcome.-

`Afurther object is to provide aclutch atv; 3o tachment of the `abovecharacter which is simple inV construction, eilicient in operation',economical'to manufacture, and adapted forready applicationto whirls .ofthe ,type indicated,'which are already in extensive use.
